DIN Standards Committee Railway

Overview

This European Standard has been drawn up with the purpose to define the minimum requirements of greases used for the lubrication of rolling bearings in railway axleboxes. The purpose is to ensure a certain performance level in the interest of operating safety in international traffic. Performance implies a certain quality level of the vehicle running gear, which every railway undertaking may require, notably by imposing procedures in approval and quality assurance for the supply of axleboxes. Lubricating greases intended for use in axlebox bearing application need to fulfil the requirements of this European Standard, complying with Table B.1. This European Standard has been written so that it reflects the typical performance of, for example, an NLGI grade 2 simple lithium soap grease, based on a mineral oil with a base oil viscosity of 100 mm²/s at 40 °C such as would be found in current use. However, this European Standard does not restrict or limit grease evolution for more demanding applications of today and in the future, hence several parameters are left open for agreement. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive 2008/57/EC. The responsible German committee is Working Committee NA 087-00-02-02 UA "Fahrwerke" ("Running gear") at DIN Standards Committee Railway (FSF).
